If you connected it that way it would still not work directly into the
wind, imagine a propeller driven boat as in Florida swamps, connect a
windmill via a direct shaft to a propellor and point it into the wind,
it would go backwards if anywhere.
I've done this, built a model, shown the theory and it will go
directly into wind. It does not go backwards. It all works on the drag
vs lift balance of the propellors involved.
I think I remember seeing a picture you posted of a model which
propelled itself by means of wheels on a solid surface, in which
the wheels were driven by a windmill.
Are you saying you also built a model *boat* driven by an *air prop*?
I'd love to see that!

If your theory was right all he'd have to do is face the thing into the wind and let the propeller start turning and off he would go at ever-increasing speeds without having to pedal because as the apparent wind speed increased so would the thrust increase and pretty soon he'd be going 100kph. ... If I consider the flow of a fluid passing through a turbine or compressor (ie wind through the wind turbine on the top, or water through the prop in the water at the bottom), then the force on that propeller/turbine will be given by the mass flow rate through the propeller disc multiplied by the change in velocity of the flow. ...
